Hi there.

10a - 35 = -8a + 1; get the variable to one side, so add 8 to both sides.

18a - 35 = 1; add 36 to both sides so we can isolate the variable.

18a = 36; divide both sides by 18 to solve for the variable.

a = 2

I hope this helps!
First start with combining and collecting like terms on different sides. So 10a+8a=35+1. 18a=36. Divide a=36/18. a=2.
